Steel sprocket characteristics
The CrMn 5045 steel sprocket's tooth ring works with the chain whenever the rear wheel receives drive. If replacing an old rear sprocket and prioritizing steel teeth, this model is an option to consider. Material alone does not determine service life. Chainline, chain slack and front sprocket condition also affect wear. If weight matters, compare the same tooth count and dimensions with the sprocket currently in use.
Selecting tooth count and chain size
The final drive ratio is calculated by dividing the rear sprocket tooth count by the front sprocket tooth count. Retain the existing rear tooth count when replacing worn parts, or select a different count if you want to change the final drive ratio and have checked the chain length. This model is available with 42 teeth. This product uses a size 525 chain. Check the markings on your bike's chain.
Checking the rear wheel assembly
Do not select Street Twin parts merely because both bikes are Triumph models. Measure the bolt-hole count, bolt circle and center bore on the actual sprocket carrier. Two sprockets with similar tooth rings may still have different mounting positions or offsets.
